Quickly
What it is
Quickly is a free, open-source platform for self-hosted cold email outreach. It creates multi-step sequences with unlimited follow-up steps, configurable waits, and automatic reply threading. Sending can rotate across Gmail and Microsoft 365 inboxes while observing each inbox’s daily limit. Integrations include Outlook, SMTP relays such as Amazon SES and Brevo, and optional IMAP reply synchronization. AI reply classification supports 19 providers, including Ollama for local offline processing. Campaign analytics show step-level performance, open, click, and reply rates, plus timeline charts. Automation options include a REST API with more than 90 endpoints, 15 webhook event types, an MCP server, and a custom n8n node. The documented security stack includes JWT HS256, bcrypt, HMAC API keys, and Fernet token encryption. Deployment paths cover Railway or other PaaS, VPS Docker Compose, existing nginx servers, and local development. The MIT license permits free use, modification, and self-hosting. The Self-hosted plan is free; server costs remain yours.
